Perlisten D215s

The Perlisten D215s is a high-end subwoofer designed to deliver exceptional sonic performance for the most demanding audiophiles and movie enthusiasts. This massive, powerful subwoofer pushes the boundaries of low-frequency reproduction, combining cutting-edge engineering with innovative technologies to provide an immersive, precise listening experience.

Colossal power in an elegant design

The D215s immediately impresses with its imposing dimensions and substantial 92 kg weight. Despite its size, Perlisten has succeeded in creating an elegant design with rounded edges and a refined black piano finish. The brand’s bronze logo adds a touch of sophistication, setting the D215s apart from more utilitarian subwoofers.

The robust HDF (High Density Fiberboard) cabinet is 80 mm thick on the front panel and 30 mm on the other sides. A complex internal bracing system ensures optimal rigidity, minimizing unwanted vibrations for pure sound reproduction.

The beating heart: two 38 cm woofers in a push-pull configuration

At the heart of the D215s are two impressive 38 cm diameter drivers, mounted in an innovative push-pull configuration. The first woofer faces forward, while the second is installed inside the cabinet, facing backward. This arrangement significantly reduces even-order harmonic distortion, improving bass precision and clarity.

The driver diaphragms are made from carbon fiber composite, combining lightness and rigidity. With a linear excursion of ±30 mm, these transducers can move large volumes of air while maintaining precise control.

Cutting-edge electronics for optimal performance

The D215s is powered by a Class D amplifier with a colossal short-term RMS output of 3000 W. This power reserve allows the subwoofer to reproduce the most dynamic passages effortlessly while maintaining a comfortable margin to prevent clipping.

Signal processing is handled by a 32-bit ARM Cortex M4 processor and a Texas Instruments DSP engine with 48-bit data paths. This computing power enables ultra-precise driver control and the implementation of advanced functions such as distortion limiting and thermal protection.

Unprecedented integration flexibility

Perlisten has equipped the D215s with a 2.4-inch LCD touch control interface on top of the cabinet. This interface provides quick access to essential settings. For more advanced control, an iOS and Android mobile app offers full access to all subwoofer parameters.

Advanced features include a 10-band parametric equalizer with 3 user presets, an adjustable low-pass filter from 30 to 160 Hz with several slopes, and variable phase adjustment from 0 to 270 degrees. These tools enable perfect integration of the D215s into any audio system.

Certified performance for the largest rooms

The D215s is THX Dominus certified, THX’s most demanding standard for large-scale home theater systems. This certification attests to the subwoofer’s ability to deliver high sound pressure levels with minimal distortion in rooms up to 184 m³.

The D215s frequency response varies according to the selected equalization mode. In “Large Room” mode, the subwoofer extends down to 15 Hz (-6 dB), delivering faithful reproduction of the lowest frequencies found in modern movie soundtracks.

Unmatched sonic precision

Measurements conducted by independent laboratories reveal exceptional distortion performance. Above 20 Hz, the D215s exhibits some of the lowest total harmonic distortion levels ever measured on a subwoofer, regardless of alignment type.

This sonic purity translates into extremely well-defined, articulate bass. The D215s excels at reproducing fast transients, delivering impactful attack and a clean stop to bass notes. This precision faithfully reproduces the nuances of low-frequency instruments such as double basses and bass drums.
